Question about 2003 Chevrolet Tahoe
People get the ignition switch confused with the key tumbler. If your key is not turning, it would be the tumbler. The actual switch is either built inthe column or on top of the column just under the dash. If your key is turning to the on position you could jimmy the starter at the S and I terminal and make the starter crank up, but if you ignition switch is bad it might not be switching to the on position. I hope you get it properly diagnosed by a qualified individual and not a guessing individual. There so many other things that need to be checked to eliminate guess work.

If you look under the hood, there is a starter relay that might be the problem - but more common than that, - Do you have an alarm system of anykind? If so, It sounds alot like that is the problem, and they are notorious for causing "no start" problems as such - Unfortunatey, the wiring for these (even to just remove one) can be rather involved (as they often cut the starter wire to install an interrupt) so you may have to take it to an auto electric shop, or one that specializes in alarm systems - Also, dealers sometimes install special "electronic lot key systems" in all of their new cars, requiring that the "electronic key" must be present in the vehicle (along with the correct physical key) in order for it to start - I'd check for one of those systems as well - Hope that helps...
